A polyamide composition which comprises a polyamide matrix having at least one novolac resin and a filler material dispersed therein, said filler material comprising nanoscale sheet structures.
A process for preparing a polyamide composition comprising at least one novolac resin and a filler material having nanoscale sheet structures, including adding such resin(s) and filler material to the monomers of the polyamide in the polymerization medium therefor, and thence polymerizing said monomers.
A process for preparing a polyamide composition comprising at least one novolac resin and a filler material having nanoscale sheet structures, including mixing the polyamide with either a compound having a structure made of sheets to be dispersed, or with a filler material having exfoliated nanoscale sheet structures.
